1.1.6.2 Ensure nodev option set on /var/log/audit partition

Information

The nodev mount option specifies that the filesystem cannot contain special devices.

Since the /var/log/audit filesystem is not intended to support devices, set this option to ensure that users cannot create block or character special devices in /var/log/audit

Solution

IF the /var/log/audit partition exists, edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /var/log/audit partition.

Example:

<device> /var/log/audit <fstype> defaults,rw,nosuid,nodev,noexec,relatime 0 0

Run the following command to remount /var/log/audit with the configured options:

# mount -o remount /var/log/audit
